Keryn asked Gary Anderson, who is running for one of two seats on the County Commission, if there was a downside to electing two rookies to the commission at the same time. He responded that he wouldn't be a total rookie since he had served on the commission 20 years ago. So he has the experience to do the job and the distance to have a fresh perspective. Interesting argument.
I mentioned to Keryn that it is also useful to remember that the Commission probably has a semi-permanent staff that will understand the day-to-day working of the office.
I heard a similar concern from a prospective temple president for an LDS temple. Having never run a temple, he was nervous about the assignment. But he didn't need to be worried. Each temple has a "recorder" that is there on the long term that worries about the day to day operations while the temple president can see to the spiritual leadership.
So being a rookie shouldn't be too much of a problem as long as there are institutional supports to make it work.
